Obviously the front couldn't be chain driven if you want to turn corners.

I'm sure I have seen it done somewhere with chain drive.
The mechanic in my LBS recently built up a front wheel with an electric assist motor in it as well.
Thinking about it, belt drive would work better for transferring drive to a front wheel. You would need a high mounted transfer drive though, so that the belt (chain) line ran along the steering axis.

SPD cleats are annoyingly expensive aren't they! instead of paying £15 for a pair i spent £21 on a new set of shimano spd pedals with SPD cleats included .
always thinking me!

Very geeky of me I know but I've just worked out that my Garmin Edge 500 can be programmed with routes before I go out along with speed targets so I can train against a virtual partner.

Wiggo ruled out of the TdF.
That settles the team leadership debate.

Yeo, did you do the Castles ride yesterday?
I couldn't make it in the end because the wife did Race for Life and I got stuck with the baby.
Very nearly bought a Giant Defy 4 t'other day. Anyone know much about them?

I was out walking yesterday, up to Barbury via Hodson then the path up to the Old Ridgeway, then along. The path from the Hodson turn to Old Ridgeway was being used for the bike ride....now if I see a mountain biker when out walking I always like to acknowledge them...so I said hello to about 40 people within about 20 mins. Couldn't have got a much better day for it...other than today, I've done maybe 10 miles....which as I'm trying to get back into something like what I used to be able to do is OK. |

a) Get/ use a pump with a flexi hose when pumping tyres up. Direct connect pumps can put stress through and tear the join between the valve and the tube (and bugger up the valve on presta). b) When you unscrew the nipple on the presta, give it a tap to unseat the core, then screw it back in a bit so that there isn't too much core sticking out. c) If you change to Schraeder, make sure your rims are drilled to take the larger diameter valve. if you have to drill yourself, do it from inside the rim (tube side) through to spoke side. |

I would agree with all of the above and also mention that I suspect that if you drill road rims to take a Schraeder valve it could be dodgy both in terms of warranty and rim strength. But if you haven't already got one get a track pump, not only is it valve friendly as mentioned above but is a game changer in terms of getting the right pressures in quickly and easily. |

Track pumps are the dogs bollocks. That is why workshops use them. They can be a bit of a bastard to lug around ona ride though  Get a frame/ pocket pump with an integral hose for use out on a ride (or a CO 2 inflator). |
